An exploration of incorporating site response into PSHA-part II: Sensitivity of hazard estimates to site response approaches

Recognising that seismic hazard assessment should incorporate site effects within a probabilistic framework and not deterministically (as usually done), the study shows, for the first time, that different choices associated with site response analysis (constitutive assumptions, model parameters and calibration procedures) impact significantly on the predicted surface hazard estimates. These findings bridge the gap between seismological research and soil dynamics, showing that the simplified deterministic route can lead to unsafe hazard estimates, and have already generated interest within SECED (Society for Earthquake and Civil Engineering Dynamics) confirmed by a well-attended invited SECED seminar in October 2012.
